EDuke32.exe works but not Mapster32.exe

Since my PC is dead I've been using my old laptop which is a Thinkpad running Win10. But there are no proper OpenGL drivers for the chipset. Some games work and some don't. I dual-boot to Ubuntu for things that won't work at all because of the OpenGL issue (like Minecraft). Strange thing is EDuke32 works in software mode (as does Ion Fury) but Mapster32 will not and just immediately dump to desktop after trying to start after the launcher even though Software mode is selected (latest version). The log says it's because my system "doesn't support OpenGL version 2 or greater. GL modes are unavailable." Obviously. I'm trying to start in software mode. Is Software mode not really software mode? Are some aspects OpenGL anyway? Or does it try to check for OpenGL regardless and fail regardless?

probably won't help, or you already done it, but try setting the couple OpenGL settings in mapster.cfg to 'no' (0 ?)

I tried compiling a build of Mapster32 with "USE_OPENGL := 0" and it hit an error looking for a polymost variable that was undeclared...

You could probably try older revisions.

I have not. I can try tonight after work.

Ah, will changing the CFG not work then? So this is some kind of regression. I'll look for an older version that works if the CFG suggestion doesn't.

Try 4593 (the build just before android) it seemed to compile without opengl, I hit a linker error but it could just be my environment mingw is too new.

I believe software blits using GL nowdays as it speeds up a LOT despite doing everything still in CPU otherwise.
There still should be a fallback for this when this fails.

Try something like early 2018 to see if it works or not.
